This invention relates'to mechanism for tudinal roove/to receive a tongue Projecting use inconnection forthe formation of flat or sheet meats into helical rolls for subse quent curlng, preserving or smok ng, and

- -5 constitutesan improvement on the machine for the same purposes shown and described in my co-pending application for'patent filed February 13, 1928, Serial No. 253,864,"l\la5 chines for preparing rolled beef.

'1 The object ofthe present invention is to provide improved devices wherebythe leading end of the meat may be quickly anchored or fixed to its supporting means forfrolling it therearound and quickly removed therefrom when the roll is formed.

Another object of the invention'is present in improved means for tying or binding the finished beef roll tightly so that it cannot unwind or loosen up in handling.

Features of the construction comprise a winding and supporting shaft having short longitudinal movement in opposite sockets and a spring to urge saidshaft'into locked position into one of the said sockets. The shaft also having pivoted spring raised spikes and longitudinal'grooves into which selected spikes may be folded and held out of operative position by devices encircl ng said shaft, which shaft has alsofa universal joint to po mit raising one end thereof to withdraw a finished roll of meat therefrom. a i

Further features include means "for permittingthe anchoring spikes a pivotal swinging movement in one direction only, the di rection toward the free end of said shaft, so that when a meat roll is properly prepared sewedand cord bound, it may be outwardly or longitudinally to free it from its supporting shaft as will bereadilj'unden stood. i c A further important feature of the invention is prominently present ina cord'tensioning and guiding block device for high tensionally binding, by a single cord, the completed compressed beef rollfor the purpose of producing a'desirable commercial package for application thereto, of a determined curing medium, such as smoke.

' Another feature of construction present i's'i'nthe provision of a shaft having a longifrom the cord carrying block body to maintain the same in fixed lateral relation there'- with? Z A still further 'fea'ture'of construction being jpresentin aflplungeroomprising ahead havnigspaced nut GXlLQDSlOIlS toengage the threads of a feed worm, the space between said extensions forming an opening through wh ch the binding cord passes on andover the said worm shaft todrive the same, the

shank "of the said head being extended upwardly through a spring chamber and having an orifice at its upper end to receive a slidable catchadapted to restupon a shoulder to maintain; the said nut extensions free of the worm threads whenthe cord'block is to be movedback to the starting point.

Briefly, the invention embodies, a rotatable shaft having hinged spring pressed spiked ,devicesthe ends of said shaft being received in oppositesockets, one socket havinga universal'joint and an enclosed spring to urge the shaft/in one direction; a worm shaft and agui'de shaft, a cord feedand tensioning blockhaving means for operatively engaging the wormfthreads to feed the'same, the cord beingthreaded through said block, thence on and over the said worm, the tensional contact with said worm being sufiicient to turn the same and toifeed said block therealong.

I clearly illustrate my invention in the accompanying drawings, which form a part of this specification and in which similar reference characters are employed to designate corresponding parts throughout the several views, in which:

Fig; l'is a front view of my improved meat roll making machine, parts being in section to more clearly disclose the construction.

relative arrangement and construction of devices employed for tensioning a cord for tightly binding a beef roll.

Fig. 4 isa fragmentary detail elevation of a device shown'in Fig. 3 with parts thereof in a different position.

Fig. 5 is a fragmentary detail of a beef roll winding and supporting shaft showing the operative and inoperative positions of hinged spikes employed.

Fig. 6 is a detail elevation of a spring pressed nut adapted to engage the feeding worm and carried by the said cord carrying trolley or block. 7

Fig. 7 shows a beef roll made and finished by the machine forming the subject matter of this application. Referring to the drawings in detail, 1 pro.- ride a frame 10 of any desired form to properly support the parts and, as here shown, it may comprise a table 11, a plate 1 2, top and bottom bars 13 and 14, and hearings in pairs, as at 15 and 16.

The plate 12, is'preferably mounted under the table 11, in suitable brackets 17 and as herein shown is formed with spaced cross bars 18, and downward directed tubular guides 19 in which guide rods 20 operate to support a bar 21, which rests on end springs 22 arranged on the guide rods 20, and on a heavier central spring 23, encircling a plunger rod 24, carrying a foot pedal 25, at its bottom.

Curved basket or cradle bars 26, are fixed to the bar 21 near its ends, and are connected at their ends by side bars ,27, having perforated ears 28, from which spaced looped chains 29 are suspended to form a basket or cradle 30 for the purpose of packing the meat as the roll progresses.

Mounted in the bearings 15 at the opposite sides of the machine frame 10 are a fixed socket 31, and a shaft 32 driven by sprockets and chain as at 33, by a motor 34, or other source of power.

The shaft 32 is connected to a short tube or socket 35 by a universal joint 36, and mount edto :rotate with the said tube isa beef rolling shaft 37, which has a cross pin 38 extending into opposite slots 39 the end of said shaft being outwardly urged by a backing spring 40, thus permitting inward sliding increment of said shaft to release its free end from the socket 31 when a beef roll is to be Withdrawn or removed therefrom, by elevating that end from the universal joint36.

. h ee rolling n supp rti g haft 37 is formed along. its length with gPOBVQs 01' channels 41 in which a number of spikes 42 are pivoted as at 43:; t ese spikes each have a shoulder 44 (Fig. 5) against which a fiat spring 45 bears, tourge andyieldingly maintein said spikes in a' ei-t'icai er eutstanding position with one side bearing against LQllBQIid ofits channel, so that the'leading dge of be: to be r lled may be pressed down over them and be carried around said shaft in its rotation.

Rings 46, are slidably mounted on the shaft 37 which are employed to hold unused spikes in their respective channels as shown in Fig. 5.

Mounted anti-frictionally in the bearings 16 is a horizontally arranged worm or screw shaft 47 and just above in the frame 10 is arranged a parallel fixed shaft 48, provided I with a longitudinal groove 49 (Figs. 3 and 4) adapted to receive a tongue 50 projecting into the bore 51, from a cord tensioning block or trolley 52 which is held in constant angular relation with the worm shaft 47 and the beef rolling shaft 37 by the tongue and groove interlocking means just described. Circular ribs 48 may be provided on the end surfaces of the block 52 around the shaft 48 to increase the bearing length thereof and to provide finished limiting surfaces for the block,

'When a beef roll has been rolled on the shaft 37 and compacted thereon by high tensional pressure exerted by the chains 29 of the basket or cradle 30 by reason of the expansive force of the springs 22-22 and 23, it is then necessary to tie the roll tightly and in practice I have found a spirally wound cord effective for that purpose, but it must be under high tension.

Satisfactory results have been attained by employing a strong cord shown at 53, which is first threaded through one or more slots in a tensioning plate 54, thence several times around a grooved pulley 55 mounted in a swivelled hanger 5-6 thence partially around and under a tensioning shoe 57. backed by a spring 58, which is adjusted by a thumb screw 59 in threaded engagement with a housing 60, ext-ending from the cord tensioning block 52 The binding cord 53 after passing under the spring pressed shoe 57, is then passed several times around another grooved pulley 61 mounted between perforated cars .62, on

the block 52, and from thence through eyes 63, also on said block. The cord is new threaded backwardly through a space 64 (Fig. 6) provided in the head 65 of a feed nut 63, around and high tensional Contact with the feed worm and thence around the meat roll 67 to which the binding cord had preriously been tied.

The high tensional engagement of the cerd 53-with the feed worm 4-7 tends to turn it and issed the cord tensioning block to the left in To release the said nut from the werig that the said block can he moved to the right to start another binding operation I p mi igl the feed 1111!: with a shank 6,8, which lest-ends through a spring 59 bearing in the nut head 65, and through a bore 7O,it l-,1e projecting end thereof having a cross opening 71 to'receiye .8 slidable catch 72 formed with a finger po tion 73 y h h th a d hark may drawn I may employ a hand needle 75, to draw a cord 76 from its roll 7 6 through the meat after which it may be tied as desired. i While the stitching and tying operations are performed and also when a new piece of beef is being spiked in place, the bar 21, supporting the basket or cradle 30 may be held in the lowered position by a latch 77"of the usual construction as will .be understood.

Obviously the constructions hereinbefore described admit of further modifications without departing fromthe spirit and scope of my invention, wherefore I desire to have it understood that I do not limit myself to the precise details shown and described.

What I claim as new, is:

1; In a machine of the class described, a shaft having recesses therein, a spike pivoted in each recess and adapted to be folded into said recess, a flat spring in said recess and a versal joint connecting said tube to said pin, and means to rotate said pin. V
